Full Idea
If tropes are basic particulars, then concrete particulars count as dependent realities. They are collections of co-located tropes, depending on these tropes as a fleet does upon its component ships.
Gist of Idea
Tropes are basic particulars, so concrete particulars are collections of co-located tropes

A Reaction
If I sail my yacht through a fleet, do I become part of it? Presumably trope theory could avoid a bundle view of objects. A bare substratum could be a magnet which attracts tropes.
